With muhidirectional and synchronous high speed forging, the radial forging machine is especially suitable for the hard deformation material forming and has become a kind of main equipment for the aeronautic shaft and tube production. The radial forging basic features are given by presenting the deformation process principles. The characteristics of mechanical drive press and hydromechanical drive press are analyzed and the limitations of these two types of radial forging machine have been presented. The hydraulic radial forging machine can flexibly change the hammer motion, the height reduction, the holding time and the forging frequency basing on the product material and shape. Therefore the hydraulic radial forging machine has a large application potential in the field of aeronautics.
